This records a scene directly from the canvas instead of through screen capture. Nothing gets scaled by the display compositor, nothing gets re-encoded twice, and you choose the bitrate. That is the whole reason the lasers band and the text goes soft when you use the macOS screen recorder. Pick a scene, add a track, press record.
This is the exact frame that gets written to the file.
Which manymoats scene fills the frame. Switching reloads it, which takes a second.
These are the levers that decide whether a laser looks like a laser or like a stack of stripes.
How much data each second of video gets. This is the single biggest lever against the banding you see on lasers and bright thin lines. Higher looks better and makes a bigger file. 16 is a good place to sit for Instagram.
Extra sharp renders the scene at 2160 by 3840 and shrinks it into the frame, which smooths the jagged stair steps on thin bright lines. It costs about four times the drawing work, so drop to Standard if the frame counter below starts sagging.
Record until you press stop, or stop by itself after a set time.
Drop an audio file here, or use the button. The file plays out loud while it records and is written into the video at the same time, off the same clock, so the picture and the sound cannot drift apart. A browser cannot pick up your Mac's system audio without installing a driver, so this is the honest way to get a real track onto a reel.
No track loaded. You can still record, the video will simply be silent.
Keep this tab in front while it records. If you switch tabs or apps, the browser stops drawing the scene and you get frozen frames.
